SPRING-WHEEL.

. Application filed. March 2, 1907.

' lowing is a specification.

The object of my invention is to provide a spring wheel tor vehicles of simple, durable and inexpensive construction in which all of the parts are readily, quickly and easily removable for purposes ot repair or replace ment and in which a maximum 0t elasticity parts moving toward each other.

is provided.

My invention consists in the construction,

( rrangement and combination ot the various of the device, whereby the objects contemplated are attained, as hereinafter more fully set torth, pointedout in my claims and illustrated in the accompanying drawings, in which Figure 1. shows a side elevationpt a vehicle wheel embodying my invention. Fig. 2 shows a sectional view of the same, and Fig. 3 shows an enlarged, detail, sectional view on the line 3-3 of Fig. 2.

Referring to the accompanying drawings,

Ihave used the reference numeral 10 to indicate the hub, 11 the spokes and 12 the telly, all ot which and are preterably made ot wood. to the periphery of the telly 12- is a corruated metal rim 13. Secured to the sides ot the telly 12 are two side plates 14 projecting beyond the telly and inclosing the rim 13. These plates are held in position by the rivets The tire ot thewheel is tormed ot a metal tire holder comprising a flat body pore extending flanges.

Secured tion 16 having outwardly 17 with laterally projecting margins 18. The tire proper is fitted to the tire holder and is indicated. by the numeral 19. It is preterably made of rubber or other yielding material. Two side plates 20 are fitted to the flanges 17 and are designed tostand within held together by means ot the rivets-21 which are provided with shoulders to" prevent the plates from are arranged in pairs, as clearly shown in 'Flg. 2, and the sprlngs each comprise a part 22 designed to enter between the rivets 0t Specification of Letters Patent.

each pair and thus be held against movement around the wheel. The-ends of each spring diverge trom each other at 23 and are corrugated at 24 to engage and lit against the corrugations ot the rim 13 to thereby prevent movement of the tire portion around the rim portion. No other fastening device for the l spring is required. In practical use, it is obvious that the tire portion may move toward and from the hub ot the wheel and thus cushion the wheel against vibration caused by the tire passing over. uneven surfaces. The tire portion is prevented trom slipping around the telly portion by means of the rivets 21 on the tire portion and the corrugated ends on the springs engaging the corrugated rim on the telly. These corrugations do not aitect the yielding movement ot the springs, but simply revent the tire from creeping upon the elly. It any of the springs should become broken or it tor any reason, it is desired to replace any or all of the springs, the operator need only remove one otthe plates 14 by loosening the rivets 15, whereupon the entire be slipped off trom the telly portion and new springs readily, and easily inserted. The overlapping plates 14 prevent the entrance ot dust or dirt within the spring chamber.

Having thus described my I claim and desire to secure by Letters Patent of the United States, therefor is 1. In a spring wheel, the combination ot a telly, a corrugated rim on the telly, a tire spaced apart trom the telly and a series ot leat springs with their central portions en gaging the tire and their ends corrugated and placed in engagement with the said corrugated rim.

2. In a spring wheel, the combination ot a telly, a'corrugated rim on the telly, a tire spaced apart from the telly, a series ot. leat springs with their central portions engaging the tire and their ends corrugated and placed in engagement with the said corrugated rim, side plates tor inclosing the springs and rivets tor connecting the side plates, said rivets serving to hold the springs against movement around the tire.
